“You can come with me,” he said. “We’ll just ride as far as New Scotland Yard.”

Triffitt felt himself turning pale. New Scotland Yard! Was he then to share his discoveries with officials? In spite of his awful veneration for the great man before him he could not prevent two words of despairing ejaculation escaping from his lips.

“The police!”

“Just so—the police,” answered Markledew, calmly. “I mean to work this in connection with them. No need to alarm yourself, young man—I know what you’re thinking. But you won’t lose any ‘kudos’—I’m quite satisfied with you so far. But we can’t do without the police—and they may be glad of even a hint from us. Now run down and get a taxi-cab and I’ll meet you outside.”

Triffitt had never been within the mazes of New Scotland Yard in his life, and had often wished that business would take him there. It was very soon plain to him, however, that his proprietor knew his way about the Criminal Investigation Department as well as he knew the Argus office. Markledew was quickly closeted with the high official who had seen Mr. Halfpenny and Mr. Tertius a few days previously; while they talked, Triffitt was left to kick his heels in a waiting-room. When he was eventually called in, he found not only the high official and Markledew, but another man whose name was presently given to him as Davidge.

“Mr. Davidge,” observed the high official, “is in charge of this case. Will you just tell him your story?”

It appeared to Triffitt that Mr. Davidge was the least impressionable, most stolid man he had ever known. Davidge showed no sign of interest; Triffitt began to wonder if anything could ever surprise him. He listened in dead silence to all that the reporter had to say; when Triffitt had finished he looked apathetically at his superior.

“I think, sir, I will just step round to Mr. Halfpenny’s office,” he remarked. “Perhaps Mr. Triffitt will accompany me?—then he and I can have a bit of a talk.”

Triffitt looked at Markledew: Markledew nodded his big head.

“Go with him,” said Markledew. “Work with him! He knows what he’s after.”
